IQF Product Specification Guides
Define the measurable product, quality, packing and approval fields needed to compare IQF frozen vegetables, fruits and mushrooms on a consistent basis.
Product identityGroup, variety where relevant, form and intended use
Measurable fieldsSize, tolerances, defects, pack and test basis
Approval pathReference sample, records, revisions and RFQ
Build the fields buyers need to define, compare and approve.
No dated specification-guide articles are currently published. Use the four product frameworks below, then confirm final values for the quoted product and partner facility.
VEGETABLES
Frozen vegetable specifications
Define product identity, cut style, dimensions, maturity, color, defect tolerances, blanching status where relevant and intended application.
FRUITS
Frozen fruit specifications
Define product identity, variety or origin where relevant, form, size, ripeness, color, Brix when relevant, defects and intended use.
MUSHROOMS
Frozen mushroom specifications
Define species, whole or cut form, size range, color, texture, defect criteria, preparation method and intended use.
METHODS
Cross-category specification skills
Structure tolerances, set a sampling and test basis, compare reference samples, confirm packing and control specification revisions.
Turn product expectations into fields a supplier can confirm.
| Specification area | Typical fields to define | Why it matters |
|---|---|---|
| Product identity | Product name, form, cut, variety or origin where relevant, and intended application | Prevents quotations or samples being based on different products. |
| Size and tolerance | Dimensions, count, size range, allowable variation and out-of-size limits | Makes size expectations measurable rather than visual only. |
| Quality criteria | Color, maturity, texture, flavor, defects, foreign material and product-specific analytical fields | Sets an agreed basis for sample and lot review. |
| Packing and labeling | Net weight, inner pack, carton, coding, label, pallet or private-label requirements | Connects the product specification to the delivered format. |
| Approval and revision | Reference sample, check method, feedback, accepted revision and approval record | Keeps the buyer, XMG and the relevant supply facility aligned. |
Apply the framework to the product you plan to buy.
The page helps your team draft comparable fields. XMG product and Quality & Supply pages show how those fields connect to product forms, sampling, packing and order evidence.
Begin with product identity and intended use. Then define measurable fields, acceptable ranges, test or inspection method, sample basis, packing and revision control.
We will prepare the brief, match the order with suitable long-term partner factories and confirm which values and records can apply to the quotation.
Use the right resource for the next sourcing question.
Connect product specifications with supplier qualification, inspection, packing, traceability and buyer-program requirements.
A complete purchase brief needs more than product fields. Use the supporting hubs for the commercial and operational context around the order.

Read the guide →Questions about the specification frameworks
Use these answers to draft a specification, compare supply options and prepare an approval step.
Start with product identity, form or cut, size, grade, measurable tolerances, defect limits, processing status, packing, test or inspection basis and intended use.
Yes. The Brix comparison guide above explains how to align sampling, preparation and temperature before comparing IQF fruit reports, and how to record the agreed method in a purchase specification.
No. Final values, methods, packing, samples, records and partner-production capability are specified for the product, destination and order.
Yes. Keep product identity, form, grade, tolerances, packing, quantity, destination and document requirements aligned before comparing price and lead time.
Send the target fields, intended application, destination and review criteria. State whether the sample is for product selection, specification confirmation or final approval.
Use a revision date or code, record the approved fields and sample basis, identify who approved the change and confirm when the new version becomes effective.
